Failover Installation

After the primary installation is complete, you install the Identity Synchronization for Windows Core
on config-eu.gt.com, and configure it using the console.

master3-eu.gt.com is the preferred Directory Server in the failover installation.

master4-eu.gt.com is the secondary Directory Server
in the failover installation.

ad3-eu.gt.com is chosen as the domain controller
with which the Active Directory Connector will communicate.

Note that a warning
will be displayed stating that the password updates might become slow
because ad3-eu.gt.com is not the PDC FSMO role owner. This warning can be ignored because changing
the PDC FSMO role to this domain controller is part of the failover procedure.
A similar warning is also displayed when the configuration is saved.

The remaining domain controllers are selected for failover during on-demand password synchronization.
